The 2020 Supra SL 400 is the kind of boat that turns heads before it even leaves the dock. Finished in a striking dark red hull, this 23-foot powerhouse combines bold aesthetics with serious performance — and at $99,999, it delivers exceptional value for a nearly-new wake boat loaded with capability. Whether you're carving up the coves of Old Hickory Lake or pulling riders on Percy Priest, this Supra is ready to make every day on the water unforgettable. Under the engine hatch lives an Indmar 400 Raptor putting out a full 400 horsepower, giving you effortless pull for wakeboarders, surfers, and skiers alike. The SL platform from Supra is known for its refined hull design and wave-shaping performance, meaning you get a clean, powerful wake without the fuss. The Raptor engine is renowned for its reliability and responsiveness — exactly what you want when you're running all day on Tennessee's beautiful reservoirs. Located in Nashville/Gallatin and ready for its next owner, this used Supra SL 400 is a rare opportunity to step into a premium wake boat at a compelling price point. Used doesn't mean compromised — it means you get premium Supra DNA and proven performance without the new-boat premium. Don't let this dark red beauty slip away.

The SL 400 holds up well when measured against its competition. Boating Magazine called it one of the best all-around wakeboats in its class, and Power Boating Magazine found it capable across every performance category. We hear similar things from owners who have surfed behind the SL consistently over multiple seasons.
Where the SL genuinely stands out is surf performance and wave-shaping technology. The onboard ballast system, intuitive stern thruster control, and AutoWake system give riders a high degree of customization without a steep learning curve. One owner noted that the SL tracks straight in surf mode, which is a real-world advantage worth knowing. Fit and finish are strong, though some forum comparisons put a competitor or two a small step ahead in that area.
Opinions on how it stacks up overall vary from owner to owner. Most who spend time behind it come away impressed, but a handful of forum voices note that the competitive segment is strong and the SL does not dramatically separate itself from the pack. For buyers who want proven surf and wake performance with solid technology built in, it covers a lot of ground.
We hear consistently strong feedback on surf performance. The combination of the Swell Surf System and standard subfloor ballast gives riders a lot of shaping flexibility, and the boat tracks straight in surf mode without pulling to one side.
The SL uses an intuitive rotating knob on the shifter to control the stern thruster, which owners find easy to dial in compared to button-based systems on some competitors.
It is genuinely strong, though a few owners who have compared it directly to competitors like Nautique rate it just a small notch below in overall fit and finish. Most find it well within the premium range.
The 2020 SL comes equipped with the Vision Control System, AutoWake System, Swell Surf System, JL Audio cabin speakers, Auto Leveling System, and a wireless charging pad as standard features.
We have seen it used by owners who compete at the pro level in surfing, so it has real pedigree in that area. Boating Magazine placed it among the best all-around wakeboats in its class.
It runs on par with strong competitors in the segment, and most owners who spend time on the water with it come away satisfied. A few forum comparisons note the segment is competitive, so there are capable alternatives, but the SL holds its own well.
